Specification of Lettersrlatent. Patented Spt, 25, 1917,

Application filed April 13, 1917. serial no'. 161,831.

To all whom may concern Be it known that I, MARTIN `OscAR NEL- soN, a citizen ofthe UnitedStates, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Window-Screens, of which the following is a specification.

The present invention relates to improveinent-s in window screens. f

In carrying out my invention it is my purpose to provide `a screen that is connected with a spring actuated roller,y the said roller being inclosed in a suitable housing to protect the same and the screen thereon from the elements when the screen is not in its lowered position, the screen having its opposite edges arranged in ways disposed to the opposite sides of the window casing while means is provided lfor retaining the screen in its lowered posltion whereby thesame will fully inclose the casing to one of the sides of the sash in thev casing and whereby either of the said sashes may' be raised or lowered without interfering with the screen. f

lIt is a further object of the invention to provide a screen that is adapted to be arranged upon a window casing, to fully cover the said casing when the screen is in its operative position and to be arranged in a suitable housing carried by the casing when the screen is in its inoperative position. Guide means are arranged vertically of the casing to receive the screen therebetween, and mea-ns Acomprising mechanism are carried bythe said guide means designed to engage with the screen to retain they screen either in an entirely lowered or partially lowered condition.

, It is a still further object of thei'nvention to produce a device of this character which may be readily secured to either the exterior or interior of any ordinary window casing, which is comparatively simple in construction, which may be readily applied toor detached from the casing and which willl perform the functions for which it is adapted with ease and with accuracy.

With'th'e above and other objects in view the improvementresides in the construction, combination and Aarrangement of parts set forth in the following specification and falling within the scope of the appended claims. l

Fig. 8 isa view similar to Fig. 7 but illustrating the guide roller for thev screen in its elevated position as when the screen is brought to cover the window casing or when the screen is wound around its roller to uncover the casing, and

Fig. 9 is an enlarged sectional view ap'- proXimately on the line 9 9 of Fig, 6.

In the drawings I have illustrated my improvement as arranged on the outer side of a window casing but it is to be understood that the same may, if desired, bev arranged upon the interior of the casing.

In the lsaid drawings, the numeral l0 designates the window casing and 1l the sill therefor. The casing 10, to the opposite sides thereof is provided with vertically arranged channel members l2 12, and be'- tween the flanges of these channel members they opposite edges of the screen are adapted to be arranged. The screen is indicated by the character 13 and is inthe nature of a wire mesh, the samebeing wound around a suitable spring actuated roller 14 that has its shafts journaled in suitable t bearings 15 1"5 secured tol the sides of the casing adjacent to the top' thereof. It will be noted that the roller I4: is disposed a suitable distance away from the channel members 12, and the numeral I6 designates a guide yrod`o'ver which the end ofthe screen istrained and whereby the edges of the' said screen areI directed to the" guide channel` members 12. The guide rodcomprises a member which is 'round' inI cross section, and the same at the opposite ends thereof is provided with" adjustable elements,- such as screws or boltsv 17 which enter the top of the casing so as to provide for the adjustment of the said rod 16 with respect lto the said top of the casing.

The screen may be arranged between guide members which are in the nature ofbars 18 and 19 arranged in pairs, the bars 19 being disposed outward of the bars 18, so that the said bars 19 will contact with the outer surface of the screen and the bars 18 with the inner surface of the said screen. The inner bars are of' a materially less length than the louterbars, the said inner bars 18 upon their lower ends being preferably vprovided with tooth portions 26 to engage with the lower member of the window casing, .the outer bars 19,l having at Atheir lower ends slotted plates 20, the outer edges of which are toothed, the said plates being engaged by headed elements whereby to adjustably connect the said toothed members to the said bars 19, while the upper or opposite ends of the said bars may be slotted or otherwise provided with a pocket to receive a plate 22, the same having its outer edge toothed as at 28 and being provided with an elongated slot 24 and the numeral 25k desig-` nates a compression element that has its shank threaded through the bar 19 and passing through the slot 24 in the plate 22, and whereby to compress the said plate 22 in the pocketof the bar 19..l Thetoothed edge 28 of the plate vis designed to engage with the upper member-of the window casing, whereby to retain vthe outer bars 19 in proper position with respect to the said casing and with respect to the spring. The

pairs of bars 18 and 19 are provided, at desired intervals, with alining openings designed to receive binding elements in .the nature of screw members 27. If desired, the bars. 18 may have. their openings in the nature of key hole slots, and the member 27 .v may have the end of its shank offset and passed through the said key hole slot, so

, that whenv the member 27 is .turned the offset end thereof, indicated by the character 28, will Contact with the inner surface of the bar 18. It is, of course, to be understoodthat the screen is provided with openingsv through which the shanks of the members 27 pass, and these' openings `may be and preferably are enforced by metallicV rivets, and the binding elements and openings ,in the screen are so arranged that the said screen may be arranged to cover one or both of the sashes'in the window casing.

The numeral 81 designatesy a suitable l housing which incloses the roller 14 and the guide rod 16 and which also is adapted to inclose the screen when the4 said screen is wound around the roller;

In practice, when the screen is not `in use it is, of course, wrapped around the-roller 14throughthe medium of the rotation of` the roller by the spring means connected therewith. When the device is in use the guide rods 19 and the compressing elements 27 associated therewith may be removed, the screen being drawn downward of the casing andguided by the channel members 12 and the guide bars 18. When the screen has been drawn to either lentirely inclose or ypartially inclose the casing, the guide barsl c 19 are arranged opposite the guide bars 18 and in contact with the screen. The binding elements 27 are then actuated to secure the screen between the bars 18 and v19.

In Figs. 6 to 9 I have illustrated a modified form of the construction. Iny these figures thel guide bars 18 and 19 are dispensed with and different means is illustrated foradjusting the guide roller for the window screen.

In the said Figs. 6 to the window casing is indicated by the character 82 and at the upper corners thereof I arrange guide members preferably in the nature of eye bolts 88 through which are passed the opposite ends of a flexible element 84 that is.

passed centrally through the screen guide roller 85. Ofl course, the ieXible elements 84 may beconnected tothe guide rollers lin a different manner if desired and instead of the single flexible element 84, two of such elements may beemployed one vsecured to 4each end of the guide roller 85. Theelement 84, as illustrated by the drawingsis,

however, inthenature'of a single membery and the portion thereof upon the outer face of the windowpcasing is'centrally connected by an operating cord member 86, while the sill of the window! casing 82 is centrally' provided with. an upstanding headed element or clip 87 designed to be engaged by the cordv 86, when the said cord is operated either in permitting the roller 85 to gravi.

tate away from contact with the upper member of thel casingl 88, as illustrated in Fig. 7 of the-drawings or into contact with the upper` member. of the casing, as illustratedin Fig. 8 ofthe drawings. The roller upon which they screen 88 is wound is indicated by the numeral 89 and has.y its shaft or trunnion spring influenced whereby the `screen88 will be normally wound around the said roller, the said shaftor trunnion being journaled in suitable bearings upon the `confronting faces of the side members of the casing82. v p y The screen 88 is designed to have its opposite edges received in and guided through channel members 41 substantially similar to the channel members 12. vThe channel members 41 are secured to the confronting vertical members of the window casingin any desired or preferred manner, and the outer ianges of the said members 41 at a suitable distance from the lower ends of the said members are cut away and in this cut away portion 1s hlngedly secured spring pressed members 42 each provided with a handle 43, the springs 44 connected between the said -members and the shafts thereof being designed to swing the members 42 inwardly toward the inner flange of the channel members 4l. By this arrangement it will be noted that the members 42 are in the nature of spring clamps and are designed when the screen is moved to the position illustrated in Fig. 6 of the draw-V ings to engage with the opposite edges of the said spring to compress the same against the inner flange of the channel member 41 to hold the screen -at a desired adjusted position upon the window casing. It is, of course, to be understood that the spring clamps 42 may if desired have their inner faces roughened or formed with projections to engage between the mesh of the screen 88.

Having thus described the invention, what I lclaim is:

l. In combination with a window casing, channel members upon the sides thereof, a spring pressed roller at the top and journaled in bearings, a screen Wound around said roller and adapted to have its edges received in the channel members, vertically disposed guide plates upon the sill arranged in pairs for receiving the screen therebetween, and means for adjustably securing the screen bet-ween the plates.

2. In combination with a window casing, channel members secured to the sides thereof, a spring actuated roller journaled in bearings at the top of the casing, a screen wound around said rollers and adapted to have its edges received in U-shaped members, an adjustable guide bar for the screen at the top of the casing, vertically disposed guide plates for the screen each comprising an inner and an outer member, means for removably securing the outer member to the casing, and means for removably securing the inner member to the outer member, and said means adapted to engage with the screen.

3. In combination with a window casing, vertically disposed U-shaped members to the sides thereof, a horizontally disposed springy .ably connect the inner to the outer plates,

the screen having openings provided with reinforcements, the said binding elements ladapted to pass through the reinforced openings to secure the screen between the guide plates.

4. In combination with a window casing, channel members upon the confronting sides thereof, a spring actuated roller at the top of the casing, a screen wound around the roller and'adapted to be received in the channel members, and means for engaging with the screen for retaining the saine between the said channel members against the influence of the spring roller.

In combination with a window casing, channel members upon the confronting sides thereof, a spring actuated roller journaled upon the sides of the casing, a screen wound around said roller, a guide roller for the screen, means associated with the guide roller and operative to move the said roller toward the horizontal member of the casing, and means for co-engaging with the screen for securing the said screen against the influence of the spring actuated roller.

In testimony whereof I aHiX my signature.
